we are currently are using the HP zbook G3 with uses a thunderbolt type dock. the dock connects to the laptop by way of a thunderbolt cable. As of now we have not been able to have the mcafee preboot environment see/work with the dock. Monitors, keyboard and mouse that are connect to the dock do not work. We are also in the process of getting some dell 5580 that also use a thunderbolt dock. My question is there a way to have the dock work in the preboot environment? Currently the user has to use the laptop screen, keyboard and mouse to get pass the logon screen. Does anyone else use these thunderbolt type docks in there environment?
